Abstract: A process for producing encapsulated semiconductor devices, which comprises using planar semiconductor-device-forming technique known  per   se  to form a plurality of spaced semiconductor devices on a wafer, etching between the devices so formed, and passivating the etched array of devices, wherein:-
     (a) the wafer is mounted on an inert solid sheet substrate;   (b) after application of the  per   se  - known semiconductor-device-forming technique to the wafer, a selective etching process is applied to divide the mounted wafer into a plurality of separate portions of the wafer material carrying semiconductor devices, each portion mounted on the substrate;   (c) a passivating process is applied to the devices to cover them with passivating material and this is followed afterwards by etching to reveal locations for ohmic connections thereon; and   (d) the devices are then separated by cutting or breaking the substrate sheet into portions carrying semiconductor devices in which no part of the semiconductor-wafer materials (except ohmic contact locations) is left uncovered by passivating material.

Abstract: An arrangement for feeding banknotes from an infeed opening (61,66) along a transport path to a storage space (26-27), comprises detecting means (e.g. 121) for detect­ing and controlling transportation of the banknotes through the arrangement; a plurality of mutually separate storage locations (26,27) in the storage space; a collect­ing location (22); a further transport path leading from the collecting location (22) to an outfeed opening (62); and command means (64). 
     The infeed opening (61,66) is constructed for the manual insertion of a bundle of banknotes (via 61), or for the insertion of a cassette (26') containing banknotes (via 66). The storage space (26-27) accommodates cassettes (26',27') of the same kind as the first mentioned cassette. Located between the infeed opening (61,66) and the casset­tes (26',27') is a first transport route (201-202, 205, 22, 260-270), which includes the collecting location (22), and a second transport route (201-202, 205', 260-270) which excludes the collecting location (22). A choice can be made between the first or the second transport routes or the second transport path respectively with the aid of the command means (64).

Abstract: Actinobacillus actinomycetemcomitans has frequently been implicated in juvenile periodontitis. The present monoclonal antibodies are specific to Actinobacillus actinomycetemcomitans. The present monoclonal antibodies are typically employed as reagents which include an inert carrier, preferably a liquid, such as buffered saline solution and a preservative. The carrier compositions are suitably selected to provide for the proper dispersal of bacteria, and to preserve the integrity of antigens and supplemental structures. The selection of the proper carrier is especially important in the detection in mixtures which include bacteria which produce large amounts of autolytic enzymes such as B. ging<sup>i</sup>valis. The monoclonal antibodies of the present invention are useful in clinical testing and differentiating antigens in the gingival or subgingival sera. The method of testing and differentiating involves the steps of contacting a sample of the bacterial flora from a lesion or other site with a measured amount of monoclonal antibody specific to a single antigen site on Actinobacillus actinomycetemcomitans and subsequently measuring the number of antibody-antigen complexes formed.

Abstract: An apertured film, suitable for use as a sanitary napkin cover which passes body fluids, is provided. The film comprises a first layer of a first polymeric material and a second layer of a second polymeric material. Both layers are apertured for the transmission of body fluids therethrough. The first polymeric material exhibits a melting point temperature which is greater than the melting point temperature exhibited by the second polymeric material. The apertured film may be thermally bonded by heating the film to a temperature in excess of the melting point temperature of the second layer material and below the melting point temperature of the first layer material. The unmelted first layer will thereby maintain the integrity of the apertured film when the second layer is in its thermally softened condition.

Abstract: The present invention is directed toward an improved etching solution which is a five component system and does not use ethylene-diamine and an etching method. Said etch solution is comprised of ethanol-amine, piperidine, water, pyrocatechol and 30% hydrogen peroxide. The solution preferably consists of 28 mls. ethanol-amine, 2 mls. piperidine, 5.5 mls. water, 5.5 grams pyrocatechol and .25 mls. hydrogen peroxide. If desired a trace of a long chain surfactant can be added to the solution. Using said method lightly doped, single crystalline silicon will be preferentially etched at an etch rate of 0.6 µm per minute ± 0.05 am per minute. The etching will effectively stop at a selectively doped level in the silicon body being etched because the etch rate of this selectively doped level drops from 0.6 um per minute to between .001 µm per minute and .0006 µm per minute.
